Vacuum phenomenon in equine carpal, metacarpophalangeal and metatarsophalangeal joints

Vacuum phenomenon in equine carpal, metacarpophalangeal and metatarsophalangeal joints.

In order to establish the incidence of vacuum phenomenon in horses' carpal, metacarpophalangeal and metatarsophalangeal joints, stress-flexed radiographs were made of normal joints, joints with known pathology and in anaesthetised horses with joints under traction. Focal intra-articular radiolucencies were identified in normal stress-flexed carpal, metacarpophalangeal and metatarsophalangeal jo...

Pyrophosphate arthropathy in the carpal and metacarpophalangeal joints.

The hand x-rays of group of patients with generalised osteoarthrosis alone were compared with those patients with generalised osteoarthrosis and chondrocalcinosis (CC). An arthropathy seemingly specific for CC could be identified in the metacarpophalangeal (MCP) and carpal joints. In the MCP joints it was characterised by subchondral rarefactions, deviation of the joint axis, joint space narrow...

MRI features of subchondral bone injury in the metacarpophalangeal and metatarsophalangeal joints of horses

[Arthroscopy of the trapeziometacarpal and metacarpophalangeal joints].

Indications for small joint arthroscopy in the hand remain poorly understood. This is due to a paucity of papers discussing this technique in the literature, as well as inadequate hands on training in the pearls and pitfalls regarding this application within the commonly used "scope" of arthroscopy. Despite the fact that small joint arthroscopes have been available for over a decade, hand surge...

Bilateral Congenital Extensor Tendons Dislocation over the Metacarpophalangeal Joints

Congenital extensor tendon dislocation over the metacarpophalangeal joint is a rare condition. Here the author presents a patient with bilateral all fingers congenital extensor tendons dislocation over the metacarpophalangeal joints. A video demonstration and ultrasound images are shown to supplement this case.
